Calories Needed Per Day:

Understanding how many calories you need is crucial for maintaining a healthy lifestyle. Whether you’re looking to lose, maintain, or gain weight, calculating your daily caloric needs is the first step. This calculator simplifies the process for you.

Formula

The formula used in this calculator is the Harris-Benedict Equation. Here’s the formula in text format:

Calories Needed Per Day = (10 * weight in kg) + (6.25 * height in cm) – (5 * age in years) + (for males: +5, for females: -161)

The result is then adjusted for your activity level by multiplying it by a factor based on your selection.

How to Use

1. Input your weight in kilograms.
2. Input your height in centimeters.
3. Enter your age in years.
4. Select your gender (Male or Female).
5. Choose your activity level from the dropdown.
6. Click the “Calculate” button.
7. The calculator will display the number of calories you need per day.

Example

Let’s say you are a 30-year-old female, weighing 65 kg, with a height of 165 cm, and you engage in moderate exercise (activity level: Moderately active). The calculator will tell you that you need approximately 1,821 calories per day to maintain your current weight.

Q2: How do I choose my activity level? A2: Select the activity level that best describes your daily physical activity. It’s essential to be honest with this choice for an accurate result.

Q3: Can I use this calculator to lose weight? A3: Yes, you can. To lose weight, you should consume fewer calories than the calculator suggests, but do so in a healthy and balanced way.

Q4: Is this calculator suitable for athletes or bodybuilders? A4: For athletes or bodybuilders with high-intensity training, you may need a more customized calculation. Consult a nutritionist or dietitian for accurate advice.

Conclusion

Knowing how many calories you need is essential for maintaining a healthy weight and lifestyle. This simple calculator provides you with a quick estimate of your daily caloric needs, based on the Harris-Benedict Equation.
